I am in Pinal county and tried Kevin Peak and Casa Grande Mountain. I didn't pick up any. I am in Florence near San Tan Valley. I am just listing to the 460 Frequency range. I don't hear as much as I did before.
Probably just using the mobile terminals mainly for dispatch. I noticed lot of law enforcement agencies do that. Works better than encryption with less grief from public and leaves the radio more clear incase something urgent does happen.
For a while, TDMA/AES talkgroups were carrying the same traffic as legacy FDMA talkgroups. That was likely a testing configuration and things reverted to FDMA-only operation; I assume there will be a cutover to TDMA/AES-only fairly soon. At the time I moved out of Arizona last month, UHF was still active in D9.
East, West and Central are all still active on both UHF and AZ WINS as of today.
Not sure when the exact date to go fully “E” is I thought I read it was supposed to be towards the end of 2027 since they were still building out the AZWINS system.
